Problems solved by technology

At the same time, the springless structure avoids the rust problem caused by the spring structure, which is safer and more hygienic, and ensures stable and reliable operation of the indwelling needle. However, this multifunctional indwelling needle still has the problem of a relatively complicated structure. , it still needs to be punctured to draw blood, and the role of the indwelling needle has not been fully exerted
[0006] CN 204601258 U discloses "a multifunctional indwelling needle", which includes a positive pressure joint, a heparin tube is arranged on the side wall of the positive pressure joint, and a blood collection device is also movably installed on the side wall of the positive pressure joint. The above-mentioned blood collection device is connected with the positive pressure joint, so that the indwelling needle has the function of blood collection, thereby reducing the pain caused by the two punctures of the patient. However, this multifunctional indwelling needle still has the problem of a relatively complicated structure and insufficient functions. At present, there is no multifunctional indwelling needle that integrates various functions and has a simpler structure

Embodiment 1

[0031] Embodiment 1: refer to figure 1 , is a structural schematic diagram of Embodiment 1 of the present invention. The multifunctional indwelling needle includes a catheter base 2, a catheter 1, a Y interface A3, an extension tube 8, a sealing clip 9, a Y interface B10 at the catheter connection seat, a catheter connection seat 12, Isolation plug 16, puncture needle 15, puncture needle seat 13 and needle handle 14 are provided with blood sampling port 7 on the side of Y interface A3, are provided with blood sampling port cap 4 on blood sampling port 7, are provided with blood sampling port cap 4 top. There is a blood collection hole 5, and a blood collection port sealing rubber 6 is provided in the blood collection hole 5. After the patient stops the infusion, the blood collection needle can be inserted into the sealing rubber 6, and blood can be collected through the blood collection port 7, without additional puncture and blood collection, which reduces the pain of the pati...

Embodiment 2

[0032] Embodiment 2: refer to figure 2 — image 3, is a schematic structural diagram of Embodiment 2 of the present invention. Compared with Embodiment 1, Embodiment 2 is different in that: both the Y interface B10 at the catheter connector and the port of the catheter connector 12 are provided with a catheter connector Thread 11 is provided with a seat cap 17 on the thread 11 of the catheter connection seat. After the infusion is stopped, the seat cap 17 can be tightened on the Y interface B10 at the catheter connection seat and the port of the catheter connection seat 12, so that it is not easy to fall off. The cleanliness of the indwelling needle can also play a certain positive pressure effect at the same time, which can prevent the backflow of blood. Cap 19, the telescopic sleeve 18 in this embodiment is a silicone sleeve. After the medical staff pulls out the puncture needle 15, they pinch the cap 19 in time, pull the puncture needle 15 into the telescopic sleeve 18, a...

Embodiment 3

[0033] Embodiment 3: refer to Figure 4 , is a structural schematic diagram of Embodiment 3 of the present invention. Compared with Embodiment 2, the difference of Embodiment 3 is that the telescopic sleeve 18 is a plastic sleeve without elasticity, and a telescopic sleeve is provided on the side of the telescopic sleeve 18 The gap 20, when not in use, the telescopic sleeve 18 is folded at the end of the puncture needle 15, and the root of the puncture needle 15 leaks outside the gap 20 of the telescopic sleeve, after the medical staff pulls out the puncture needle 15, they pinch the sleeve cap 19 in time Pull the sleeve cap 19 to the tip of the puncture needle 15, the puncture needle 15 is pulled into the telescopic sleeve 18 through the telescopic sleeve gap 20, and the needle tip is stuck on the sleeve cap 19, which can prevent the puncture needle 15 from hurting the medical staff and also It can prevent other personnel from being stabbed and causing infection, the structur...

Abstract

The invention discloses a multifunctional indwelling needle. A blood collection mouth is arranged at the side surface of a Y interface A of the indwelling needle, wherein the blood collection mouth can be used for collecting blood. An airbag is arranged in a catheter seat, not only is the Y interface A blocked, but also the blood is prevented from flowing counter. A buckle is arranged at the outer side of the catheter seat, thus the indwelling needle in the patient's arms and the like is fixed more firmly. A telescopic sleeve is arranged on a puncture needle seat located at the tail end of a puncture needle; a cap bag is arranged on the top end of the telescopic sleeve, wherein the cap bag can pull the puncture needle into the telescopic sleeve to prevent stabbing falsely. Rubberized fabrics and telescopic nets are arranged at the outer side of the catheter seat, Y interface A and buckle respectively, thereby fixing the indwelling needle in the patient's arms and the like more firmly. Compared to the prior art, the multifunctional indwelling needle has the advantages of collecting the blood conveniently; preventing the blood from flowing counter and stabbing falsely; being fixed more firmly in the patient's arms and the like; possessing various functions; being simple in structure, more secure and more reliable.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a multifunctional indwelling needle. Background technique [0002] The venous indwelling needle is also called the venous trocar. The core components include a soft catheter that can be indwelled in the blood vessel, and a stainless steel puncture guide core. When in use, the catheter and the needle core are punctured into the blood vessel together. After the blood vessel, the needle core is withdrawn, and only the soft catheter is left in the blood vessel for infusion therapy. It is easy to puncture, and the relevant puncture techniques are easy to learn to protect the patient's blood vessels, relieve the patient's pain, feel comfortable, and improve patient satisfaction and care. Quality, avoiding multiple intermittent infusions every day, reducing puncture and not taking medication on time, avoiding drug reactions, reducing costs, and reducing the cost of exudation treatment cau...
